There is no in-person requirement in Pennsylvania’s constitution..
what voting rule change in Pennsylvania are you wanting me to look at.
Is this it:
WASHINGTON — The Supreme Court will allow Pennsylvania to count mailed-in ballots received up to three days after the Nov. 3 election, rejecting a Republican plea in the presidential battleground state.
The justices divided 4-4 on Monday, an outcome that upholds
a state Supreme Court ruling that required county election officials to receive and count mailed-in ballots that arrive up until Nov. 6, even if they don't have a clear postmark, as long as there is not proof it was mailed after the polls closed.
